Hello, I have really bad screen flickering happening on my UX31A. I opened the BIOS and it is still happening there. I am attempting an update to the newest operating system, but I fear that it will not work. Here is a link to a movie I took of the screen. Would somebody confirm that this is a Motherboard issue? Does anyone know what the fix might be? Thanks, Dylan

Hi, Try connecting an external monitor and check whether its’ display is also flickering. If if doesn’t, then it might not be a problem with the GPU but possibly could be either:

  1. faulty video cable between motherboard and screen (press around the screen ‘hinges’ area (this is where the cable passes through from the body to the lid) and see if you can make it better or worse.
  2. faulty video cable connection either on the motherboard or on the screen.
  3. faulty backlight power supply feed or lid sensor when the lid is closed or opened a signal is sent to the relevant section on the motherboard which sends a signal to the screen to software turn on / turn off the backlighting.
  4. faulty LCD screen If it does, then there is a problem with the GPU on the motherboard. Here is a link to a video showing the dis-assembly of your laptop, which may be of some help.

For me the issue was a dockingstation (I have UtechSmart 1:12 usb-c to outputs) this probably limited the amount of energy the display could get and caused the flickering. My problem still is that I can’t use 3rd monitor without my dockingstation as my laptop doesn’t have enough ports. I guess my main lesson is make sure you are not overextending any one input. In my case is was the usb 3 thunderbolt port which I tried to connect too much too via the dockingstation
